Check Digit Verification of cas no

The CAS Registry Mumber 1438436-41-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,8,4,3 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1438436-41:
(9*1)+(8*4)+(7*3)+(6*8)+(5*4)+(4*3)+(3*6)+(2*4)+(1*1)=169
169 % 10 = 9
So 1438436-41-9 is a valid CAS Registry Number.

Sterically controlled, palladium-catalyzed intermolecular amination of arenes

Shrestha, Ruja,Mukherjee, Paramita,Tan, Yichen,Litman, Zachary C.,Hartwig, John F.

supporting information, p. 8480 - 8483 (2013/07/19)

We report the Pd-catalyzed amination of arenes to form N-aryl phthalimides with regioselectivity controlled predominantly by steric effects. Mono-, di-, and trisubstituted arenes lacking a directing group undergo amination reactions with moderate to high yields and high regioselectivities from sequential addition of PhI(OAc)2 as an oxidant in the presence of Pd(OAc) 2 as catalyst. This sterically derived selectivity contrasts that for analogous arene acetoxylation.
